Wait about 15 minutes before eating any more. Be careful not to eat too much. This can cause high blood sugar and weight gain.

Check your blood sugar again.

If you do not feel better in 15 minutes and your blood sugar is still lower than 70 mg/dL, eat something with 15 grams of carbohydrate again.

You may need to eat a snack with carbohydrates and protein if your blood sugar is in a safer range -- over 70 mg/dL -- and your next meal is more than an hour away.

Ask your doctor or nurse how to manage this situation. If these steps for raising your blood sugar do not work, call your doctor right away.

Talk to your doctor or nurse

If you use insulin and your blood sugar is frequent or consistently low, ask your doctor or nurse if you:

Are injecting your insulin the right way

Need a different type of needle

Should change how much insulin you take

Should change the kind of insulin you take

Do not make any changes without talking to your doctor or nurse first.

Sometimes hypoglycemia can be due to taking the wrong medicines. Check your medicines with your pharmacist.

When to call the doctor

If signs of low blood sugar do not improve after you have eaten a snack that contains sugar, have someone drive you to the emergency room or call your local emergency number (such as 911). Do not drive when your blood sugar is low.

Get medical help right away for a person with low blood sugar if the person is not alert or cannot be awakened.
